WATER-COOLER FOR ENGINES.

Specification of Letters Patent.

essence.

appliances, and relates more particularly to devices for the calculation and cooling of the water or other liquid of an engine cooling system.

It is the object of the invention to provide a water cooler for internal combustion engines of compact, simple and inexpensive construction for efiiciently cooling the water by siphonic action without the use of a circulating pump, piping and like equipment.

Another object is the provision of a water cooler assembled with the engine water jacket in a novel yet simple manner, to avoid piping and similar connections, and to establish quite to rapid circulation of the water, even without the use of a pump, the Water jacket being so arranged as to interchangeably use a radiator, hopper cooler and pipe connections.

A further object is to'provide a radiator of novel and improved construction to efiicaciously carry out the principles of the invention.

l/Vith the foregoing and other objects in view, which will be apparent as the nature of the invention is better understood, the invention resides in the construction and arrangements of parts hereinafter described and claimed, it being understood that changes can be made within the scope of what is hereinafter claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of an engine and a' radiator. embodying the features of the invention, assembled therewith.

Fig. 2 is a side elevation of a hopper cooler attached to the water jacket of the the water jacket'showing engine in place of the radiator.

Fig. 3 is a fragmentary side elevation of how pipe connections can be used interchangeably with the radiator andhopper cooler.

Fig. i is a face view of the radiator, portions being broken away.

Fig. 5 is a side elevation thereof.

Fig. 6 is a fragmentary rear view.

In carrying out the invention, it is preferable to have the engine cylinder inclined, as seen in Fig. 1, so that its water jacket 1 is similarly arranged, and said acket is equipped at its upper side with the Water outlet and inlet abutments 2 and 3, respectively, adjacent to the upper and lower ends of the jacket. By thus tilting the engine cylinder and its jacket and providing said jacket w'th the water outlet and inlet abutments, the engine is particularly adapted for the direct attachment of the cooler.

The radiator at is attached directly to the jacket 1, above the same but in an uprightposition, and for this purpose, said radiator is provided at one lower corner with an inclined portion 5 provided adjacent to its upper and lower ends with water inlet and outlet abutments 6 and 7, respectively, to complement and seat on the abutments 2 and 3, respectively, in order that the openings of said abutments will register for the flow of water or other liquid in a circuitous path between the jacket and radiator. The in clined portion 5 of the radiator with its water inlet and outlet therefore provide for the direct and effective connection of the radiatorv or cooler with the water jacket, with the radiator extending upwardly and to one side from the jacket. The direct connection of the radiator with the jacket eliminates piping and like connections, and alsoof the radiator to be cooled, and the cooled liquid in the radiator will pass to the bot-- tom and flow back into the jacket through the abutments 7 and 3. The cooler water in the jacket will naturally settle to the lowermost portion thereof and as it absorbs heat from the cylinder will rise and again flow to the radiator, to keep up the-circulation as long as the engine is in operation.

Fig, 2 illustrates a hopper cooler used in inclined portion of the radiator, to adapt the tank 4 to the inclined jacket 1, and said portion 5 has the water inlet and outletabutments 6 and 7 at its upper and lower ends to be secured to the abutments 2 and 3,

respectively, for the circulation of water. The tank 4: has a partition or baflie 8 projecting from the portion 5 immediately above the water outlet toward the opposite side, to prevent the direct flow of the water from the inlet along the portion 5, to the outlet, and constraining the water to flow in the directions of the arrowsfin Fig. 2.

Fig. 3 depictshow pipe connections 6" and 7 can be fastened on the abutments 2 and 3, respectively, when such connections are desired.

Now taking up the detail construction of the radiator, which has characteristic features for its intended purposes, the same includes a sheet metal or other suitable casing 9 having an inner wall 10 circumscribing an opening 11 which extends through the cas ing for the passage of air, while the outer wall 12 of the casing extends around and is spaced from the inner wall 10, thus providing a chamber extending completely around the opening 11. The walls 10 and 12 have the lower inclined portions 13 and 14, respectively, extending diagonally from the bottom to one side, and providing the inclined portion 5 of the radiator as above described. Vertical water tubes 15 are arranged within the opening 11 and their upper ends extend through the upper portion of the wall 10,- while their lower ends extend through the inclined portion 13 and bottom portion of said wall, so as to permit the water to flow downwardly in small streams from the upper portion of the water chamber to the lower portion thereof. Webs 16 'of anysuitable sort are assembled with the tubes 15 within the opening 11 to dissipate the heat to the atmosphere, andthus cool the water in the tubes 15, so that it flows downwardly therein. The casing 9 can be filled in any suitablemanner, such as by providing the same with an upper filling neck 17 hav ing a removable cap 18 thereon.

The abutments 6 and 7 which are assembled with the inclined )ortion 14 of the outer wall 12, are prefera ly part of a metal casting which fits against and is secured to the portion 5 of the radiator, said casting having the web 14 connecting the abutments 6 and 7 and riveted or otherwise securedto the portion 14. This casting also has the flanges 23 at its upper and lower ends extending at an angle from the abutments 6 and 7 and overlapping and riveted or otherwise secured to the bottom and respective side of the wall12, thus firmly fastening the casing 9 and casting together, and said casting or attachin member is provided at the opposite sides ot the radiator with outstand ing apertured ears 24' projecting from the abutments for the reception of bolts or other securing means to fasten the abutments 6 and 7 on the respective abutments 2 and 3 of the water jacket 1. The abutments 6 and 7 have the respective openin s'20 and 21 to register with the openings oi the abutments 2 and 3, for the flow of water therethrough as aforesaid, the portion 14: also having openings 22 registering with the openings 20 and 21. The opening 20 provides the inlet of the radiator below the short side thereof, while the opening 21 provides the outlet arranged substantially midway between the opposite sides, and in order to compel the hot water to flow upwardly from the opening 20, instead. of flowing downwardly in the inclined passage between the portions 13 and 14, a partition or bafiie 25 is provided between the opening 20 and said passage. This partition 25 is disposed above the opening 20, and has its upper edge soldered or otherwise secured, as at 26, to the wall 10 at the upper end of the portion 13, whereas the lower edge of the partition is soldered or otherwise secured, as at 27, on the portion 14; next below the opening 20. The water must therefore flow upwardly from the opening or inlet 20 in the vertical passage in the short side of the casing 9 to the upper p0rtion of the water chamber for the downward fiow of the water in the tubes 15 and vertical passage in the long side of the casing. From the lower ends of the tubes 15 the water fiows along, converging lines in the V- shaped passage in the lower portion of the casing below the tubes, to the opening or outlet 21 near the angle of said passage.

Fitted within that lower corner of the easing 9 opposite the portion 5, is a sheet metal which fits against the wall 12 within the corner thereof. Said membcr'is riveted or otherwise secured to the wall 12, and the upper end of the member has an inwardly extending stiffening flange 29. A flanged socket member 30 is secured to the inner side of the upright portion of the member 28, and has a threaded socket 31 opening through the member 28 and wall 12 for the reception of a bolt 32, 'as seen in Fig. 1, or

as shown in dotted lines in Fig. 4, forthe attachment of a brace at this point, if desired.
